I’ve just started building a little tank game in Flash that I’d like to eventually make in XNA. Right now, the goal is to create a classic arena battle verses several enemy tanks. At the moment, I’ve got a controllable player tank with firing capability and a set of targets that are randomly placed on the screen. The next step will be creating wall objects and possibly a map generator.

Controls:
left and right arrows rotate tank
up and down arrows move tank
shift and control rotate turret
space fires cannon
1 adds more targets
